Description

TECHNICAL FIELD

[0001] The utility model belongs to water conservancy equipment technical field, concretely relates to a vertical-lift gate. BACKGROUND

[0002] The vertical-lift gate is a control facility for closing and opening water flow passage, which mainly adjusts water flow by controlling vertical lifting of the gate plate, and is suitable for small and medium-sized hydraulic structures, and can realize functions of intercepting water flow, controlling water level and adjusting flow. When the gate needs to be opened, the opening and closing machine (such as a hoist) drives the gate plate to vertically rise, so as to open the water flow passage; when the gate needs to be closed, the opening and closing machine drives the gate plate to vertically descend until a closed state is formed.

[0003] In the existing design of the vertical-lift gate, a sealing element is generally arranged on the gate plate. The main function of the sealing element is to ensure that the gate can effectively prevent water flow from passing through the small gap between the gate and the gate slot in the closed state, thereby playing a water-stopping role. In order to improve the sealing effect, the sealing element must maintain a high degree of close-fitting state when the gate is closed.

[0004] However, if the sealing element still maintains the close-fitting state during the opening of the gate, a large friction force will be generated, which not only greatly reduces the service life of the sealing element, so that the sealing effect after long-term use cannot be guaranteed, but also increases the movement resistance of the gate, thereby causing the energy consumption of the opening and closing machine to increase. TECHNICAL SOLUTION

[0065] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0066] Example:

[0067] like Figure 1 As shown in the figure, this application discloses a vertical lifting gate for closing and opening water flow channels. The specific structure includes: a gate frame assembly 1, a gate body assembly 2, and a lifting mechanism 3.

[0068] like Figure 6 As shown, the door frame assembly 1 includes: a bottom frame plate 11, two side frames 12, and a supporting crossbeam 13, which are configured as follows:

[0069] The bottom frame plate 11 is horizontally arranged and installed at the bottom of the water flow channel outlet, flush with it, to provide a stable supporting foundation; such as Figure 2 Furthermore, a second layer of concrete can be poured at the bottom to improve the stability of the support;

[0070] Two side frames 12 are disposed opposite to each other on the left and right sides of the top surface of the bottom frame plate 11, and are installed on both sides of the water flow channel outlet, and are flush with it, for supporting and guiding the lifting and lowering movement of the door assembly 2. Each side frame 12 specifically includes:

[0071] The side frame plate 121 has a vertical groove 1211 with a top opening on the inner side. The vertical groove 1211 has an L-shaped cross-section and includes a sealing groove 12111 and a mounting groove 12112 located at the bottom of the sealing groove 12111.

[0072] A plurality of pressing units 122 are vertically spaced apart, each of which comprises a pressing block 1221 arranged in the pressing groove 12111 and a support assembly 1222 mounted on the side frame plate 121, and the support assembly 1222 is connected with the pressing block 1221 for laterally supporting the pressing block 1221;

[0073] The support beam 13 is horizontally arranged between the two side frame plates 121, providing additional support and stability, and is mounted on the top of the outlet of the water flow channel and flush with it, used to fit the back top end of the door body assembly 2 to enhance the sealing performance. Figure 3 As shown, the concrete can also be poured again on one side close to the dam body to improve the structural stability.

[0074] As shown in Figures 2-5 and Figure 7 The door body assembly 2 comprises a shutter body 21, a sealing plate 22 and a plurality of pressure blocks 23, which are arranged as follows:

[0075] The shutter body 21 is vertically arranged and vertically inserted into the installation groove 12112 on the left and right sides, respectively, as the main water retaining structure;

[0076] The sealing plate 22 is arranged on the back of the shutter body 21 and can simultaneously fit the left and right sides with the inner wall of the installation groove 12112, the bottom surface with the bottom frame plate 11, and the back top end with the support beam 13.

[0077] The plurality of pressure blocks 23 are arranged on the left and right sides of the front of the shutter body 21 and located in the pressing groove 12111, and correspond one-to-one with the pressing blocks 1221, for bearing the pressure applied by the pressing blocks 1221 and uniformly transmitting the pressure to the shutter body 21.

[0078] Exemplarily, the pressure blocks 23 are arranged at four corners of the front of the shutter body 21 to ensure uniform stress and improve the sealing effect, but are not limited thereto.

[0079] The lifting mechanism 3 is located above the door frame assembly 1 and is specifically mounted on the support platform above the outlet of the water flow channel and is in transmission connection with the shutter body 21 for driving the door body assembly 2 to move up and down.

[0080] The pressing block 1221 has a pressing surface 12211 for contacting the pressure block 23, and the pressing surface 12211 is arranged from top to bottom gradually inclined to the side close to the shutter body 21 to ensure that the pressure block 23 can be gradually extruded during the process of sliding down along the pressing surface 12211.

[0081] The above technical solution works as follows:

[0082] When the gate is closed, the lifting mechanism 3 drives the gate body 21 to vertically descend, so that the gate body 21 gradually descends along the installation groove 12112 on both sides, and the pressure block 23 moves downward in the sealing groove 12111; then the pressure block 23 contacts the pressing surface 12211 of the pressing block 1221 in the corresponding pressing unit 122, and since the pressing surface 12211 is inclined, the pressure block 23 is gradually extruded during the downward movement, and the pressure is transmitted to the gate body 21, and the gate body 21 transmits the pressure to the sealing plate 22, so that when the door body assembly 2 is lowered to the bottom, the left and right sides of the sealing plate 22 are tightly attached to the inner wall of 12113, the bottom surface is tightly attached to the bottom frame plate 11, and the back top is tightly attached to the support beam 13, so as to ensure the sealing effect.

[0083] When the gate is opened, the lifting mechanism 3 drives the gate body 21 to vertically ascend, so that the pressure block 23 is no longer extruded during the upward movement, and therefore the sealing plate 22 gradually loosens and separates, the frictional force on the sealing plate 22 gradually decreases until zero, which prolongs the service life, ensures the sealing effect after long-term use, reduces the movement resistance of the gate, and reduces the energy consumption of the lifting mechanism 3.

[0084] The utility model discloses a plurality of pressure blocks 23 are arranged on the left and right sides of the front of the gate body 21, and the pressure block 23 is gradually extruded by the pressing block 1221 during the downward movement, so that when the door body assembly 2 is lowered to the bottom, the sealing plate 22 can be pressed to be tightly attached, which not only ensures the sealing effect when the gate is closed, but also avoids the sealing plate 22 from being severely rubbed when the gate is opened, thereby prolonging the service life, ensuring the sealing effect after long-term use, reducing the movement resistance of the gate, and reducing the energy consumption of the lifting mechanism 3.

[0085] In some embodiments, as shown in Figures 2-5 The sealing plate 22 includes a sealing middle plate 221, a sealing horizontal strip 222 and two sealing vertical strips 223; the sealing horizontal strip 222 is arranged at the top end of the sealing middle plate 221, and the two sealing vertical strips 223 are arranged on the left and right sides of the sealing middle plate 221.

[0086] Exemplarily, the sealing horizontal strip 222 and the sealing vertical strip 223 are both hollow round rod structures, which are easy to deform after being pressed, thereby expanding the contact area and improving the sealing effect.

[0087] Exemplarily, the sealing plate 22 is made of rubber, which has the characteristics of small elastic modulus and high elongation, and can deform greatly when subjected to external force, thereby effectively compensating for the sealing gap.

[0088] During sealing, the bottom surface of the sealing plate 221 is in close contact with the bottom frame plate 11, the sealing horizontal strip 222 is in close contact with the supporting horizontal beam 13, and the sealing vertical strip 223 is in close contact with the inner wall of the side frame plate 121 near the water flow channel.

[0089] The above design of the sealing plate 22 significantly improves the sealing effect, while requiring less material and resulting in lower manufacturing costs.

[0090] Based on the above embodiments, the door assembly 2 includes: a pressure plate 24, which is attached to the back of the sealing middle plate 221 and bolted to the gate body 21, for pressing and fixing the sealing plate 22 to improve the structural stability.

[0091] In some embodiments, such as Figure 1 , Figure 3 , Figure 5 , Figure 7 As shown, the gate body 21 includes: a gate panel 211, two angle steels 212 and two strips 213; wherein, the two angle steels 212 are arranged opposite each other and are vertically set on the left and right sides in front of the gate panel 211; the two strips 213 are horizontally set on the upper and lower sides in front of the gate panel 211 and are connected to the angle steels 212.

[0092] The above design of the gate body 21 significantly improves the structural strength and enhances the structural stability, while using less material and reducing manufacturing costs.

[0093] Based on the above embodiments, such as Figures 1-3 As shown, the gate body 21 includes: reinforcing ribs 214 and multiple support plates 215, which are configured as follows:

[0094] The reinforcing rib 214 is located in front of the door panel 211 and is connected to two strips 213 on the top and bottom sides, and to two angle steels 212 on the left and right sides.

[0095] Multiple support plates 215 are horizontally arranged inside the angle steel 212 and connected to the front of the door panel 211. They correspond one-to-one with the pressure block 23 and are used to support the pressure block 23 to reduce the force on the bending point of the angle steel 212.

[0096] For example, the reinforcing rib 214 has a cross-shaped structure, which has a good supporting effect and uses less material; however, it is not limited to this and can also be a grid-shaped structure, without specific limitation.

[0097] The above-mentioned design further improves the structural strength and rigidity of the gate body 21, effectively disperses stress, thereby enhancing the overall load-bearing capacity, and reduces the amount of material used while ensuring performance, thus reducing production costs.

[0098] In some embodiments, such asFigure 3 As shown, the support assembly 1222 comprises:

[0099] a plurality of adjusting bolts 12221 arranged at intervals and screwed into the side frame plate 121 and the compression block 1221;

[0102] Illustratively, the adjusting bolts 12221, the inner adjusting nuts 12222 and the outer adjusting nuts 12223 are provided in two, but are not limited thereto, and more can be provided.

[0103] In use, the lateral position of the compression block 1221 can be adjusted by the extension amount of the adjusting bolts 12221, so as to adjust the compression degree on the gate body 21.

[0104] Through the above arrangement, the support stability is ensured, and the lateral displacement of the compression block 1221 can be adjusted, which facilitates assembly and debugging, and the structure is simple and compact, and easy to disassemble and assemble.

[0105] In some embodiments, as shown in Figure 1 and Figures 4-6 The side frame 12 comprises a plurality of reinforcing plates 123 and a plurality of connecting plates 124, which are arranged as follows:

[0106] The plurality of reinforcing plates 123 are horizontally arranged and vertically spaced and arranged outside the side frame plate 121, for enhancing the structural strength and rigidity of the side frame plate 121 and preventing deformation;

[0107] The plurality of connecting plates 124 are vertically arranged and vertically spaced and arranged on the inner side of the side frame plate 121, and a plurality of mounting holes 1241 are formed in the connecting plate 124;

[0108] In installation, the connecting plate 124 is attached to the outer side of the dam body, and the expansion bolts are screwed into the dam body through the mounting holes 1241, so as to complete the installation and fixation of the side frame 12.

[0109] Preferably, the connecting plate 124 is fixedly connected to the adjacent reinforcing plate 123, thereby playing a supporting role, thereby reducing stress concentration and enhancing the connection stability of the connecting plate 124.

[0110] Through the above arrangement, the structural strength and rigidity of the side frame 12 are improved, and the stability of the installation is enhanced, the installation operation is simplified, and the installation efficiency is improved.

[0111] In some embodiments, as shown in Figure 2 and Figure 3 The bottom frame plate 11 is in a concave structure with an opening facing downward, and the support beam 13 is in an L-shaped structure.

[0116] The boom 33 is vertically arranged, and the top end is threadedly connected with the lower end of the shaft coupling nut 32, and the bottom end is hingedly connected with the top surface center of the gate body 21.

[0117] Exemplarily, the top surface of the gate body 21 is provided with an eye, and a plurality of reinforcing plates are arranged on the gate body 21, so as to improve the hinging stability and ensure the use safety.
